Abstract :
High-spin states in 136Nd were populated via the 100Mo(40Ar, 4n) reaction at beam energies of 176 and 182 MeV, and resulting γ-rays were detected using the GAMMASPHERE spectrometer. Analysis of the data has revealed the existence of an excited superdeformed (SD) band in 136Nd. The yrast SD band in 136Nd has been extended by the addition of four (possibly five) transitions at high frequency. The new band displays the remarkable property of having transition energies identical (to within ± 1 keV) to those of the half-points of the yrast SD band of 136Nd. Possible explanations in terms of cranked Woods-Saxon single-particle calculations are discussed.
